I purchased and installed a Ford Performance Finned Differential Cover to help keep things cool. I used the gasket from Yukon Gear recommended by American Muscle. I noticed a couple of things that seemed odd: (1) it took way more gear oil than I anticipated. I was expecting a little over two quarts. It took 7! Where did it go? It's not all over the floor of the garage. (2) when I torqued the bolts down, they started to feel like they were going to strip, so I didn't get all the way down to 33 ft pounds. Maybe I should have stopped at 25? I read differing opinions. It does have a very slight drip starting to form, so I'm questioning the gasket and the torque on the bolts.
